To all whom it'. may concern.'

y Be it known that I, HARRY B. WrNrrELD, a citizen of the United States, residing at Gresham, in the county of Multnomah and State of Oregon, have invented certain new and useful lmprovements in l'renches, of which the following is a specification.

The object of this invention is a simple, durable and efficient construction ofw-rench which is particularly adapted foruse in confined places since it maybe conveniently o erated by the reciprocation of the hand e, and whicheinbdies primarily relatively sta-- tionary alligator aws that may be rigidly held in diferentpositions in angular relation to the handle, according as desired.

With. this and other objects in view that will more fully appear as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parte` that l shall hereinafter fully describe and then point out the novel features thereof in the appended claim.

F or a full-understanding of the'invention and the merits thereof, reference is to'be had Vto the following description and the accompanying drawing, in which:

igure 1 is a proved wrench ig. 2 is a plan view thereof partly broken away; Fig. 3 is a longitudinal section; and, Fig. 4 is a detail view showing the pawls in an inoperative position.V v

Corresponding and like parts are referred to in the. following description and indicated in all the views of the drawing lby the saine reference characters.

Referring to the drawing, the numeral 1 designates the handle of my improved wrench, which is formed at its front end with a longitudinal recess 2 communicating with the," sides of the handle and forming two spaced members 3. The spaced members 3 are formed at their side edges, near their rear ends, with outstanding alining ears 4, the end wall of the recess 2 being sloped rearwardly near such ears, as indicated at A head `6 is pivotally mounted between the spaced members 3, and is formed at one end with a V-shaped opening -7 forming two relatively stationary converglng jaws 8, the edge i of one of which is preferabl serrated, as shown. The other end 9 of tie head is segmental ni forln and is provided at its edge Specification of Letters Patent.

j with a series of teeth 10. These teeth are designed to be engaged by the forward ends of two pawls 11 that are pivotally. mounted nea-r their rear ends at the opposite sides' of the handle and between the corres onding ears 4 by'means of screws 12 or the li e passing therethrough. The awls are normally j held inengagement witli the teeth 10 by means of two flat springs 13 secured to the having their front ends outwardly disposed and arranged to bear against the pawls. rlhe pawls 11 are formed at their outer edges wvith angularly disposed bearing surfaces 14 and 15, the springs 13 normally pressing against the bearing surfaces 14 to hold the forward ends of the pawls in engagement When the pawls 11 are moved outwardly so that the enlargements formed at the junction of the-bearing sursprings 13 are arranged to press against the bearing surfaces 15 lto hold the pawls in an inoperative position out of engagement with vthe teeth. lWhen ,the ment with the teeth, the rear ends of the former are arranged to abut against the sloping portions 5 ofthe end wall of the recess 2, so as to relieve the screws or other pivots 12 from excessive strain.

In 'the practical use of my improved wrench, the pawls 11 are disengaged from the teeth l0, and the head 6 is rotated so that the alligator 'aws 8 thereof are at the desired angle to the handle 1, said awls being then rengaged with the teeti to hold the head rigidly in adjusted position. By throwing the required pawl out of engagement with the teeth, the head 6 may be ro' tated to a limited extent by the reciprocation of the handle.4

Having thus described the invention, what I claim is A wrench comprising a handle having a recess at its front end forming spaced members, said-members being formed near their rear ends with outstanding alining ears, the

ward suchl ears, a head formednat one end lwith jaws, the other end of the'headbeing i segmental and formed with a plurality ot vteeth, said head being pivotally mounted at such latter end between the spaced members,

faces 14 and 15 are swung past a center, thef end wall of the recess sloping rearwardly tosides of the handle behind the ears 4, and

pawls 11 are in engagcy and pawls pivotally mounted between the In testimony whereof l aiix my signature coiglresponding fears and having thleirforwalld in presence of two witnesses en s mranffed or e-nffagement Wit i t e teet 1, Y 1 the rear @riads of vthebpawis being adapted to HARRY B' VVINBIELD [L' S] 5 bear against the sloping portions of the end Witnesses:
